Purpose: The purpose of the study was to obtain information on factors leading to perioperative dissatisfaction of patients who undergo orthognathic surgery for dentofacial deformities. Materials and Methods: A total of 44 patients who underwent orthognathic surgery between January 1, 2003, and September 30, 2005, were included in this study. All patients completed 21-item questionnaires, which were analyzed using the frequency distribution and the χ2 test. Results: The patients lost 6.4% of their body weight after 1-jaw surgery and 6.7% after 2-jaw surgery. The patients returned to their everyday life 4.8 weeks after 1-jaw surgery and 5.2 weeks after 2-jaw surgery. Restoration of sensory function after jaw surgery required almost 10 weeks. Conclusion: Written information about possible sequelae and the recovery period and patients' consent to the surgical procedure may be helpful in proper communication, which may reduce patients' perioperative dissatisfaction.
